Final answer:
The given statement "A frame-by-frame analysis of a slow-motion video shows that a hovering dragonfly takes 8 frames to complete one wing beat". is true.
The correct answer is option (B) False
Step-by-step explanation:
In physics, the time taken to complete one wing beat can be calculated using the formula:
Time = Number of Frames x Time per Frame
In this case, the number of frames is given as 8, and the time per frame can be determined by knowing the frame rate of the video.
Therefore, if the frame rate of the video is known, the time taken for one wing beat can be determined.
Thus, the correct answer is option (B) False
